That' depends on the mission. A rocket and a space shuttle have to be in orbit and so have to fly at 8 km/s. But in certain cases, the rocket has to leave the earth (apollo, planet probe...), and then these rocket have to fly at 11 km/s. So usually the speed are the same, but sometimes, rocket are faster...

Sonic is faster than shadow because shadow basically cheats. He doesn't run, he skates and has rocket shoes. Sonic just runs, with no tricks.
Most rockets are much faster than fighter aircraft.
